Bad CPU

Bad CPU
I have a '98 Mazda B3000, 106K, that does not start easily and has horrible preformance. I have replaced the wires, plugs, #2 O2 sensor in the last 6 months and the fuel pump TWICE in the last two years.
I had a complete diagnostic done yesterday and the mechanic thinks that my CPU is bad. There is no comunication from it to any of the O2 sensors, fuel system, notta. A repacement runs about $850.00, not in my budget, so I was thinking of pulling one from a junkyard and plugging it in? Will this work, are there any after market options where I might be able to increase preformance?
Thanks

Mazda running poorly
When you changed those plugs, did you by chance install a new distributor cap? I Had a Mazda 929 running like crap and was told I needed a new computer...turned out to be my new Bosch distributor cap causing the misfires! Replaced it with Japanese brand (Denso I think) , problem solved.

It's fuel injected so, no distributer cap. Now I'm getting a code of P1131, a "Manufacter Specific Powertrain trouble Code", which the dealer says has to do with the air fuel mixtuer? Dealer also said there is a TSB that deals with problems similar to what I have been experincing, TSB is about a grounding issue at wiring location X309? Any thoughts on where that might be?
Thanks
Thanks
